    im running electrics, on a 350 crate. the thing i read reccomended dual 14" fans, which is what im running. the truck now runs 5-ish degrees hotter than before, but at the same time, i can watch my temp gauge drop when i pull to a red lite. im gonna try a lower temp thermostat, and see what it does for me. i think that might be the ticket.

    I run a single IROC electric fan on my TPI406 motor. Don't know what the CFM is on it. No problems with cooling at all, ever. Also have a 4 core radiator.
